Understanding the China EN 853 2SN Hydraulic Hose

Hydraulic hoses play a crucial role in various industrial applications, facilitating the transfer of fluids under pressure. Among the many standards and specifications that govern the production of hydraulic hoses, the China EN 853 2SN standard stands out for its reliability and versatility. In this article, we will explore the key features, applications, and benefits of the China EN 853 2SN hydraulic hose.

Overview of the EN 853 2SN Standard

The EN 853 2SN standard outlines specific requirements for hydraulic rubber hoses used for medium to high-pressure applications. This standard, originally established in Europe, has been adopted in various markets, including China, to ensure uniform quality and performance. The 2SN designation refers to a two-wire braided construction that provides enhanced flexibility, strength, and durability.

The design of the 2SN hydraulic hose typically consists of three main components the inner tube, the reinforcement layer, and the outer cover.

1. Inner Tube The inner tube is made of synthetic rubber, which is resistant to hydraulic fluids, heat, and aging. This ensures that the hose can withstand high pressures without leaking or bursting. 2. Reinforcement Layer The unique feature of the 2SN hose is its reinforcement layer, which consists of two layers of steel wire braid. This braided construction significantly enhances the hose's strength and allows it to handle higher pressures compared to single-wire hoses.

3. Outer Cover The outer cover is crafted from weather-resistant rubber, designed to protect the hose from external factors like UV radiation, ozone, and abrasion. This added protection extends the lifespan of the hose, making it suitable for both indoor and outdoor applications.

Key Features

The China EN 853 2SN hydraulic hose is renowned for its exceptional performance characteristics. Some of the standout features include

- High Pressure Resistance The hose is designed to operate at pressures up to 400 bar (approximately 5800 psi), making it suitable for various hydraulic applications. - Versatility This type of hose is compatible with a wide range of hydraulic fluids, including oil-based fluids, water-glycol, and water-based solutions, thereby broadening its application scope.

- Flexibility The double-wire braided construction allows for greater flexibility compared to other hose types, enabling ease of installation in tight spaces.

- Temperature Resistance With a temperature range typically from -40°C to 100°C (-40°F to 212°F), the 2SN hose performs well in diverse environments.

Applications

The China EN 853 2SN hydraulic hose finds extensive use across various industries. Some common applications include

- Agriculture Used in tractors and other agricultural machinery for fluid transfer in hydraulic systems. - Construction Essential in construction equipment like excavators and loaders, where high-pressure hydraulic systems are required for operation.

- Automotive Utilized in hydraulic brake systems and power steering systems within vehicles.

- Mining Employed for hydraulic systems in machinery used in mining operations, where high pressures and challenging conditions are prevalent.

Conclusion

In summary, the China EN 853 2SN hydraulic hose exemplifies quality and reliability in fluid transfer applications. Its robust construction, high-pressure capacity, and versatility make it a top choice in various sectors, including agriculture, construction, automotive, and mining. As industries continue to evolve, the demand for efficient and durable hydraulic hoses will rise, ensuring that the China EN 853 2SN remains a pivotal component in hydraulic systems worldwide. Whether you are an engineer, technician, or procurement specialist, understanding the benefits and applications of this hydraulic hose will help you make informed decisions for your operations.
